That market is driven by extremely wealthy "space enthusiasts," 925 of whom already have made reservations to fly into space. In the growth scenario outlined in the report, that number could climb to 11,000 over the next ten years.

The more conservative baseline scenario predicts 3,600 seats on suborbital flights will be filled, generating $600 million. The constrained scenario, calculated based on shrinking budgets, predicts 2,000, for $300 million.

The growth forecast is based on a scenario in which "Commercial Human Spaceflight has a transformative effect on consumer behavior," leading to more interest in the industry.

The numbers are based on The Tauri Group's survey of wealthy individuals, polling of suborbital researchers, and open source materials including market studies and government budgets. Its writers estimate that of interested individuals with the necessary funds, 40 percent will actually fly.
